Problems solved by technology

[0002] As we all know, the tower crane hoist is an indispensable lifting equipment in the construction industry. The machine is used for loading and unloading operations between shore and ship, and ship and ship. The disadvantages are: the progress of loading and unloading bulk cargo is slow, the energy consumption is high, the labor intensity of workers is high, and the work efficiency is low; there are tower cranes used in construction. The tower body is formed by fixing the upper and lower ends of the unit steel frame. The upper end of the tower body is equipped with a jacking frame, and the lower end is fixed with the support seat. The hydraulic cylinder is connected with the tower body, and the jacking cylinder is driven by a hydraulic self-lifting motor. A luffing motor, a lifting motor and a slewing motor are installed on the slewing arm to control the lifting and slewing of the tower when lifting building materials. One end of the slewing arm is equipped with There is a lifting hook, and the other end is equipped with a counterweight. When working, the skip with materials is transferred to the designated floor through the lifting hook. The disadvantages are: unreasonable structure, single function, low working efficiency, and low The workload only accounts for 30%, and 70% is idle, which is not conducive to the construction of large buildings

After the floors are initially completed, for high-rise building operations, the concrete is generally transported to the construction site of the high-rise building through pipelines by means of concrete pumping. The building is equipped with a set of pumping risers. The investment in the pumping risers is very large, the power consumption is large, and the cost is high

For low-altitude pouring operations, the concrete hoist is usually equipped with a horizontal guide wheel and a wire pulley on the jacking frame of the tower body. The wire rope passes through the horizontal guide wheel and the wire pulley. One end is connected to the ground winch through the guide wheel, and the other end is connected to the skip. There is an unloading track and ash storage bucket on one side of the tower body, and the lifting track is set in the center of the tower body. When working, the skip filled with concrete is lifted to the corresponding floor, so that the concrete is unloaded into the ash storage bucket, and then loaded into the ash bucket. Casting by trolley, its disadvantages are: the structure is unreasonable, one is that the hoist can only lift one ash storage bucket material every time it works one cycle, the energy consumption is large, the work efficiency is low, and the construction progress is long. The concrete in the ash storage hopper can be loaded into the trolley only by pushing the trolley through the channel built between the floor and the tower, which is poor in safety
